THREAD-HOLDER FOR SPINDLES.

SPECIFICATION forming part of Letters Patent No. 578,810, dated March16, 1897.

Application filed February 15, 1896. Serial No. 579,389. No model.)

To all whom it may concern.-

Be it known that I, OLIVER C. BURR, a citizen of the United States ofAmerica, residing at Vvestvale, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inThread- Holders for Spindles; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to provide a cheap, simple, andeffective means for holding the end of the thread or yarn to be woundupon the bobbin; and it consists in providing the spindle with a fixedcollar beneath which is loosely mounted a collar having pins which passthrough apertures in the fixed collar, the loose collar beingspring-actuated toward the fixed collar to hold the yarn between saidcollars, such construction provid ing means for holding the end of thethread or yarn during the process of doffing instead of winding a numberof turns on the spindle, as is the common practice, thus effecting agreat saving in time and material, as there is no accumulation or wasteof yarn below the bobbin.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical sectional view showing a spiddle provided with myimproved thread-holder, the parts being in position for holding thethread between the collars. Fig. 2 is a side elevation showing thebobbin pressed down upon the spindle to separate the collars and releasethe thread; and Fig. 3 is a detail perspective view showing the partsseparated, the construction of the collars being slightly modified.

A designates the spindle, which is provided with a bobbin-holder A ofthe type known to the trade as Burrs Patent Bobbin-Holder. The spindleis also provided with a fixed collar B, having vertical apertures 17 b,through which pass pins 0 0, carried by a looselymounted collar C,located below the fixed collar. Against the under side of thelooselymounted collar 0 bears a helical spring D,

which encircles the spindle and bears at its lower end upon a ring d,attached to the spindle. This spring acts to force the loose collaragainst the fixed collar, and when the collars are together the pins 0project above the upper edge of the fixed collar.

The adjoining edges of the collars B and C are preferably beveled, asshown, so that the end of the thread or yarn can be readily guidedbetween said collars, and, if desired, one of the collars may beprovided with an annular flange and the other with a correspondingsocket, as shown in Fig. 3, so that the parts will fit one within theother and give a better hold or grip upon the yarn.

Over the spindle and upon the upper ends of the pins 0 is placed awasher E, against which the lower end of the bobbin will bear whenplaced in position upon the spindle.

The device hereinbefore described can be readily applied to spindlesalready manufactured, and the opening in the washer being smaller indiameter than the bobbin-holder A will be retained in position thereby.

In operation the end of the thread or yarn is placed between the collarsB and C, and the bobbin being placed upon the spindle to bear lightlyupon the upper ends of thepins the thread or yarn is guided so as to bewrapped upon the lower part of the bobbin a sufficient number of timesto insure its engagement therewith, after which the bobbin is forceddown upon the upper ends of the pins 0 to move the collar C away fromthe collarB and thus release the end of the thread. When the bobbin hasbeen filled, the yarn is placed between the collars, so that when saidbobbin is removed the thread or yarn will be broken between the bobbinand the collars and the end held thereby.

This invention provides a very simple, cheap, and effective means forholding the end of the thread or yarn until the wrapping of the sameupon the bobbin has been fairly started.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a thread-holder for spindles, the combination with a revolublespindle having a fixed member thereon, of a second member independent ofthe fixed member and reciprocally mounted on the spindle, means to movesaid member away from the fixed member controlled by the bobbin as it isplaced on the spindle, and a spring for actuating the movable memberagainst the movement imparted thereto by the bobbin.

2. The combination with the spindle, of a collar fixed thereon, a secondcollar movable on the spindle and spring-actuated against the fixedcollar, and pins projecting from the movable collar and adapted tocontact with the bobbin when said bobbin is placed upon the spindle,substantially as shown and for the purpose set forth.

3. The combination with the spindle A having a fixed collar or ring, ofa movable collar or ring having pins which project above the fixedcollar or ring, and a spring mounted upon the spindle and in engagementwith the movable collar, the bobbin when placed upon the spindle beingadapted to'bear against the upper ends of the pins, substantially asshown and for the purpose set forth.

4. In a thread-holder for spindles, the combination of a spindle havinga suitable bobbin-holder mounted thereon, a fixed collar mounted uponthe spindle below the bobbinholder, a movable collar located below the vfixed collar and provided with pins which project above the same, and aspring mounted on the spindle so as to force the movable collar againstthe fixed collar, the parts being organized substantially as shown andfor the purpose set forth.

5. The combination withthe spindle A having a fixed collar B mountedthereon and provided with vertical apertures 19 b, of a movable collarhaving pins which pass through the apertures in the fixed collar, aspring mounted upon the spindle to bear against the movable collar, anda washer E mounted upon the spindle to rest upon the upper ends of thepins; together with a bobbin-holder carried by the spindle above thewasher, the parts being organized substantially as shown and for thepurpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

OLIVER C. BURR.
